Which component to upgrade to help stream

[vazquez.matthew25]

I have been streaming on twitch (mostly fortnite) and my streams look good while i am still but get pixelated while i’m building and moving a lot. I have a i5 4690 K and a GTX 1050 ti. Which one should i upgrade to help the stream quality more.
